An agricultural seed mixing device for planting

Abstract

This utility model relates to the field of agricultural planting technology and discloses an agricultural seed mixing device, including a fixed frame. The device, through a cleaning component, allows the connecting frame to drive a brush to clean a filter plate when the cylinder extends. Upon contact with the mounting plate, the action of a first abutment rod and an inclined plane compresses a first spring, causing the brush to detach from the filter plate. Simultaneously, a connecting block pushes a moving block, and under the action of a second spring, a limiting block engages with a limiting groove, thus limiting the slider and preventing the brush from carrying back impurities when the cylinder retracts. When the cylinder retracts until the connecting frame contacts the baffle, the second abutment rod inserts into a second insertion hole, and the inclined plane pushes the moving block out of the limiting groove, releasing the limiting position. The first spring releases and drives the brush to reset, re-attaching to the filter plate. This structure achieves automatic reset and unidirectional operation during the filter plate cleaning process, effectively preventing impurities from being carried back, and improving cleaning efficiency and automation.

Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to an agricultural seed mixing device for agricultural planting. Background Technology

[0002] In agricultural production, to ensure seed germination rates and control pests and diseases, seeds often need to be mixed with specific fertilizers, pesticides, and other agents before sowing. This process requires a high degree of uniformity in agent distribution and accuracy in dosage, so specialized mixing equipment is usually required.

[0003] A search revealed an agricultural seed mixing device for planting, with publication number CN221553858U. This application uses a filter plate to allow excess pesticides and fertilizers to be discharged through the feed channel onto the filter plate, filtered, and then collected in a collection box. This reduces pesticide and fertilizer waste, facilitates reuse, and increases the utilization rate of pesticides and fertilizers.

[0004] However, during the mixing process, the fluid discharged from the feed channel is not solely pure residual pesticide solution; it inevitably contains dust from the seeds, broken seed particles, seed coats, and other light impurities. These solid impurities flow with the liquid to the filter plate and quickly accumulate on its surface, clogging the filter pores. This requires manual cleaning of the filter plate by the operator. This process is time-consuming and labor-intensive, severely impacting operational efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an agricultural seed mixing device for agricultural planting, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an agricultural seed mixing device for agricultural planting, comprising a fixed frame, a motor fixed on the outer surface of the fixed frame, the output shaft of the motor passing through the fixed frame, a stirring roller rotatably connected to the inner wall of the fixed frame, the output shaft of the motor fixed on the outer surface of the stirring roller, a feed inlet opened on the outer surface of the fixed frame, a baffle fixed on the right outer surface of the fixed frame, a filter plate fixed on the outer surface of the baffle, and a cleaning component and a movable component provided on the outer surface of the baffle;

[0007] The cleaning component includes:

[0008] A cylinder is used to provide power.

[0009] Connecting frame, used to stabilize the internal and surface mechanisms;

[0010] The slider is used to drive the cleaning mechanism to perform the cleaning work.

[0011] Limiting components are used to achieve unidirectional cleaning and prevent items from being carried back.

[0012] Preferably, the cylinder is fixed to the outer surface of the baffle, the output end of the cylinder passes through the baffle, and a connecting frame is fixed to the output end of the cylinder. A slider is slidably connected to the inner wall of the connecting frame, and a spring is fixed to the top of the slider. The top of the spring is fixed to the inner wall of the connecting frame. When the cylinder is activated, it performs a reciprocating extension and retraction motion. The connecting frame moves closer to the abutment rod, causing the brush to clean the surface of the filter plate.

[0013] Preferably, the limiting component includes a connecting block, which is fixed to the top of the slider. The outer surface of the connecting block has an abutment groove. The right side of the connecting frame has an insertion hole. The right outer surface of the fixing frame is fixed with a mounting plate. An abutment rod is fixed to the side of the mounting plate near the connecting frame. A fixing plate is fixed to the top of the inner wall of the connecting frame. A spring is fixed to the outer surface of the fixing plate. A moving block is fixed to the end of the spring away from the fixing plate. The moving block is slidably connected to the top of the inner wall of the connecting frame. A limiting block is fixed to the side of the moving block away from the spring. A limiting groove is formed on the outer surface of the connecting block. An abutment rod is fixed to the inner side of the baffle. An insertion hole is formed on the left side of the connecting frame. An abutment groove is formed on the outer surface of the moving block. When the connecting frame is in contact with the outer surface of the mounting plate, the abutment rod is inserted into the insertion hole and abuts against the inclined surface of the abutment groove, pushing the connecting block and slider upwards, causing the brush to detach from the filter plate. Simultaneously, the limiting block enters the limiting groove, with its side away from the inclined surface abutting against the inner wall of the limiting groove, thus limiting the movement of the connecting block and the slider. When the cylinder retracts, the brush will not carry back impurities, avoiding affecting cleaning efficiency. When the connecting frame is in contact with the baffle surface, the second abutting rod inserts into the second insertion hole and abuts against the inclined surface of the second abutting groove, pushing the moving block and the limiting block out of the limiting groove, releasing the limitation. The slider and brush reset and re-attach to the top of the filter plate, achieving unidirectional cleaning.

[0014] Preferably, the movable component includes a fixed frame, which is fixed to the outer surface of the connecting frame. A movable column is slidably connected to the inner wall of the fixed frame. A spring is fixed to the top of the movable column, and the top of the spring is fixed to the top of the inner wall of the fixed frame. A protrusion is fixed to the top of the filter plate. When the connecting frame moves back and forth, the movable column reciprocates and abuts against the outer surface of the protrusion. The spring does not affect the normal movement of the movable column, so that when the movable column abuts against the protrusion, it drives the filter plate to vibrate, thus preventing impurities from adhering.

[0015] Preferably, a box is installed below the fixing frame, and a filling port is opened on the top of the box. A pump body is fixed on the outer surface of the box. The input end of the pump body passes through the box, and a spray pipe is fixed on the output end of the pump body. The end of the spray pipe away from the pump body passes through the fixing frame. A collection box is placed below the right end of the fixing frame. When the motor and pump body are turned on, the stirring roller drives the seeds to tumble and convey them. At the same time, the pump body sprays the medicine solution onto the seed surface through the spray pipe for drug processing.

[0016] Preferably, a brush is fixed to the bottom of the slider to facilitate cleaning impurities on the surface of the filter plate.

[0017] Preferably, both the first and second contact grooves are set as inclined surfaces. When the inclined surface of the first contact groove is contacted, it can drive the slider to move upward. When the inclined surface of the second contact groove is contacted, it can drive the moving block and the limiting block to disengage from the limiting groove.

[0018] Preferably, the cross-section of the limiting block is a right-angled triangle, with its side away from the inclined surface abutting against the inner wall of the limiting groove, which can limit the connecting block and the slider. When its inclined surface is abutted, it can drive the moving block to move away from the connecting block.

[0019] Compared with the prior art, this utility model provides an agricultural seed mixing device for agricultural planting, which has the following beneficial effects:

[0020] 1. This agricultural seed mixing device for planting utilizes a cleaning assembly. When the cylinder extends, the connecting frame drives the brush to clean the filter plate. Upon contact with the mounting plate, the action of the first abutment rod and the inclined plane compresses the first spring, causing the brush to detach from the filter plate. Simultaneously, the connecting block pushes the moving block, and under the action of the second spring, the limiting block engages with the limiting groove, thus limiting the slider and preventing the brush from carrying back impurities when the cylinder retracts. When the cylinder retracts until the connecting frame contacts the baffle, the second abutment rod inserts into the second insertion hole, and the inclined plane pushes the moving block out of the limiting groove, releasing the limiting position. The first spring releases and drives the brush to reset, re-attaching to the filter plate. This structure achieves automatic reset and unidirectional operation during the filter plate cleaning process, effectively preventing impurities from being carried back, and improving cleaning efficiency and automation.

[0021] 2. This agricultural seed mixing device for agricultural planting, through its movable components, causes the movable column to reciprocate against the outer surface of the protrusion when the connecting frame moves back and forth. Through the spring three, the movable column can move back and forth without affecting its normal movement, and it also drives the filter plate to vibrate, preventing impurities from adhering and improving its cleaning efficiency.

[0029] like Figures 1-6 As shown, this utility model provides a technical solution: an agricultural seed mixing device for agricultural planting, including a fixed frame 1, a motor 2 fixed on the outer surface of the fixed frame 1, the output shaft of the motor 2 passing through the fixed frame 1, a stirring roller 13 rotatably connected to the inner wall of the fixed frame 1, the output shaft of the motor 2 fixed on the outer surface of the stirring roller 13, a feed inlet 3 opened on the outer surface of the fixed frame 1, a baffle 11 fixed on the right outer surface of the fixed frame 1, and a filter plate 12 fixed on the outer surface of the baffle 11. The outer surface of the baffle 11 is provided with a cleaning component 8 and a movable component 9; the cleaning component 8 includes: a cylinder 80, a connecting frame 81, a slider 82, a first spring 83, a limiting member 84, a connecting block 840, a first contact groove 841, a first insertion hole 842, a mounting plate 843, a first contact rod 844, a fixing plate 845, a second spring 846, a second contact groove 847, a limiting groove 848, a limiting block 849, a second contact rod 8400, a second insertion hole 8401, and a moving block 8402.

[0030] Cylinder 80 is fixed to the outer surface of baffle 11. The output end of cylinder 80 passes through baffle 11, and a connecting frame 81 is fixed to the output end of cylinder 80. A slider 82 is slidably connected to the inner wall of connecting frame 81. A spring 83 is fixed to the top of slider 82, and the top of spring 83 is fixed to the inner wall of connecting frame 81. Limiting member 84 includes connecting block 840, which is fixed to the top of slider 82. An abutment groove 841 is opened on the outer surface of connecting block 840. An insertion hole 842 is opened on the right side of connecting frame 81. A mounting plate 843 is fixed to the outer right side of fixing bracket 1. An abutment rod 844 is fixed to the side of mounting plate 843 near connecting frame 81. A fixing plate 845 is fixed to the top of the inner wall of connecting frame 81. A second spring 846 is fixed to the outer surface of plate 845. A movable block 8402 is fixed to the end of the second spring 846 away from the fixed plate 845. The movable block 8402 is slidably connected to the top of the inner wall of the connecting frame 81. A limit block 849 is fixed to the side of the movable block 8402 away from the second spring 846. A limit groove 848 is opened on the outer surface of the connecting block 840. A second abutment rod 8400 is fixed to the inner side of the baffle 11. A second insertion hole 8401 is opened on the left side of the connecting frame 81. A second abutment groove 847 is opened on the outer surface of the movable block 8402. A brush is fixed to the bottom of the slider 82. Both the first abutment groove 841 and the second abutment groove 847 are set as inclined surfaces. The cross-section of the limit block 849 is a right-angled triangle. The cylinder 80 is activated to perform reciprocating extension and retraction movement. When the cylinder 80 extends, the connecting frame 81 moves closer to the first abutment rod 844, driving the brush to clean the surface of the filter plate 12. When the connecting frame 81 is attached to the outer surface of the mounting plate 843, the first abutment rod 844 is inserted into the first insertion hole 842 and abuts against the inclined surface of the first abutment groove 841, pushing the connecting block 840 and the slider 82 upward, while simultaneously compressing the first spring 83, causing the brush to detach from the filter plate 12. At this time, the top of the connecting block 840 abuts against the inclined surface of the limiting block 849, pushing the moving block 8402 away from the connecting block 840; when the limiting block 849 is aligned with the limiting groove 848, the second spring 846 is released, pushing the moving block 8402 back to its original position, causing the limiting block 849 to enter the limiting groove 848, with its side away from the inclined surface abutting against the inner wall of the limiting groove 848, thus limiting the connection block 840 and the slider 82. When the cylinder 80 retracts, the brush will not carry back impurities, avoiding affecting the cleaning efficiency. When the connecting frame 81 is in contact with the surface of the baffle 11, the second abutment rod 8400 is inserted into the second insertion hole 8401 and abuts against the inclined surface of the second abutment groove 847, pushing the moving block 8402 and the limiting block 849 out of the limiting groove 848, thus releasing the limit. Subsequently, the first spring 83 is released, causing the slider 82 and the brush to reset and re-attach to the top of the filter plate 12, achieving unidirectional cleaning, improving cleaning efficiency, and eliminating the need for manual intervention.

[0031] The movable component 9 includes a fixed frame 90, which is fixed to the outer surface of the connecting frame 81. A movable column 91 is slidably connected to the inner wall of the fixed frame 90. A spring 92 is fixed to the top of the movable column 91. The top of the spring 92 is fixed to the top of the inner wall of the fixed frame 90. A protrusion 93 is fixed to the top of the filter plate 12. When the connecting frame 81 moves back and forth, the movable column 91 reciprocates and abuts against the outer surface of the protrusion 93, causing the filter plate 12 to vibrate and preventing impurities from adhering.

[0032] A box 4 is installed below the fixed frame 1. A filling port 6 is opened on the top of the box 4. A pump body 5 is fixed on the outer surface of the box 4. The input end of the pump body 5 passes through the box 4. A spray pipe 7 is fixed on the output end of the pump body 5. The end of the spray pipe 7 away from the pump body 5 passes through the fixed frame 1. A collection box 10 is placed below the right end of the fixed frame 1. When the motor 2 and the pump body 5 are turned on, the stirring roller 13 can drive the seeds to turn and convey them. At the same time, the pump body 5 sprays the medicine liquid onto the surface of the seeds through the spray pipe 7 for drug processing.

[0033] In use, seeds are fed into the fixed frame 1 through the feed inlet 3, and the medicine is added through the filling port 6. At this time, the motor 2 and pump 5 are turned on, causing the stirring roller 13 to rotate and convey the seeds. Simultaneously, the pump 5 sprays the medicine onto the seed surface through the spray pipe 7 for processing. To collect the seeds, the collection box is placed at the front end of the filter plate 12. The filter plate 12 filters and collects the medicine, causing it to drip back into the collection box 10. If the filter plate 12 becomes clogged, the cylinder 80 is activated to reciprocate. When the cylinder 80 extends, the connecting frame 81 moves closer to the contact rod 844, allowing the brush to clean the surface of the filter plate 12. When the connecting frame 81 is in contact with the outer surface of the mounting plate 843, the contact rod 844 enters the insertion hole 842 and abuts against the inclined surface of the contact groove 841, thereby driving the connecting block 840 and the slider 82 to move upward. At the same time, the spring 83 is compressed, and the brush disengages from the filter plate 12. Simultaneously, as the connecting block 840 moves upward, its top abuts against the inclined surface of the limiting block 849, which in turn drives... The moving block 8402 moves away from the connecting block 840. When the position of the limiting block 849 is parallel to the limiting groove 848, the second spring 846 is released, causing the moving block 8402 to reset, so that the limiting block 849 enters the limiting groove 848. At this time, the side of the limiting block 849 away from the inclined surface abuts against the inner wall of the limiting groove 848, which can limit the connecting block 840 and the slider 82. When the cylinder 80 retracts, the brush will not bring back impurities, avoiding affecting the cleaning efficiency. When the connecting frame 81 is in contact with the surface of the baffle 11, the second abutment rod 840... The 0 enters the second insertion hole 8401 and abuts against the inclined surface of the second contact groove 847, thereby causing the moving block 8402 and the limiting block 849 to disengage from the limiting groove 848, thus releasing the limit. At this time, the spring 83 is released, driving the slider 82 and the brush to reset and re-attach to the top of the filter plate 12, thus achieving unidirectional cleaning, improving cleaning efficiency, and eliminating the need for manual cleaning. At the same time, when the connecting frame 81 moves back and forth, the movable column 91 abuts against the outer surface of the protrusion 93, which causes the filter plate 12 to vibrate, preventing impurities from adhering and improving cleaning efficiency.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
